如何在iOS13的状态栏上叠加视图

Question

fileprivate lazy var netTipWindow:UIWindow = {
        let window = UIWindow(frame: CGRect(x: 0, y: topMargins, width: UIScreenW, height: realheight))
        window.backgroundColor = .clear
        window.windowLevel = .alert
        window.isHidden = false
        window.rootViewController = UIViewController()
        window.rootViewController?.view.addSubview(self)
        frame = CGRect(x: 0, y: -(topMargins + realheight), width: UIScreenW, height: realheight)
        return window
    }()

我的代码在ios 12中运行良好，但效果与图片类似。

另外，我尝试了这段代码，没有区别

    fileprivate lazy var netTipWindow:UIWindow = {
        let window = UIWindow(frame: CGRect(x: 0, y: topMargins, width: UIScreenW, height: realheight))
        window.backgroundColor = .clear
        window.windowLevel = .alert
        window.isHidden = false
        if #available(iOS 13, *) {
            window.addSubview(self)
        } else {
            window.rootViewController = UIViewController()
            window.rootViewController?.view.addSubview(self)
        }
        frame = CGRect(x: 0, y: -(topMargins + realheight), width: UIScreenW, height: realheight)
        return window
    }()

iOS 13状态栏

Answer 1

这段代码....

- (BOOL)prefersStatusBarHidden {
    if (@available(iOS 13.0, *)) {
        // safearea iPhone x, xr ..
        if ([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.top > 20.0) {
            return NO;
        }
        else {
            return YES;
        }
    }
    else {
        return NO;
    }
}
